Environmental Regulation of Gut Microbial Networks Links to Growth Variation in Schizopygopsis younghusbandi Across Contrasting Aquaculture Systems

< 0.05), highlighting environmental regulation of microbial assemblages. Overall, the aquaculture environment shapes gut microbial networks, which closely relate to growth performance. Recirculating aquaculture systems can mitigate growth limitations in plateau fish by stabilizing the environment and reinforcing gut microbial communities, providing a sustainable strategy for high-altitude aquaculture development.
